NAME

       sane-gphoto2 - SANE backend for gphoto2 supported cameras


DESCRIPTION

       The  sane-gphoto2  library  implements a SANE (Scanner Access Now Easy)
       backend that provides  access  to  the  digital  cameras  supported  by
       gphoto2.   This  backend has only been tested with a handful of cameras
       so far.  Patches to support other models are welcome.

       Because of the limited testing of this backend, it is commented out  in
       /etc/sane.d/dll.conf  by default.  Either the comment character must be
       removed or the backend must be called explicitly.  E.g.  `scanimage  -d
       gphoto2' or `xscanimage gphoto2'.


DEVICE NAMES

       The  current  version  of the backend only allows one camera to be con‐
       nected.  The device name is always "0".


CONFIGURATION

       The contents of the gphoto2.conf specify  the  characteristics  of  the
       camera  to be used.   Resolutions (high resolution, low resolution, and
       thumbnail size) are required since they are needed by  the  sane  fron‐
       tends,  but  can't  be  obtained  through the gphoto2 interface.  Valid
       ports and cameras can  be  obtained  by  "gphoto2  --list-cameras"  and
       "gphoto2 --list-ports".

       The  dumpinquiry  line  causes  some information about the camera to be
       printed.

       Empty lines and lines starting with a hash mark  (#)  are  ignored.   A
       sample configuration file is shown below:

       The  "topfolder" line specifies the "fixed" part of the file path.  For
       example, on the  Kodak  DC-240,  files  are  stored  in  the  directory
       /DCIM/100DC240.   The  /DCIM  portion  is  constant,  but 100DC240 will
       change and must be read from the camera.  In this case, the line  would
       read "topfolder=/DCIM"

       Some cameras don't implement a file structure and store all pictures in
       the "/" directory.  This is indicated by setting "subdirs=0" with "top‐
       folder=/"

              port=usb:
              camera=Kodak DC240
              # this is a comment
              high_resolution=1280x960
              low_resolution=640x480
              thumb_resolution=160x120
              dumpinquiry


FILES

       /etc/sane.d/gphoto2.conf
              The   backend   configuration  file  (see  also  description  of
              SANE_CONFIG_DIR below).

       /usr/lib64/sane/libsane-gphoto2.a
              The static library implementing this backend.

       /usr/lib64/sane/libsane-gphoto2.so
              The shared library implementing this backend (present on systems
              that support dynamic loading).



ENVIRONMENT

       SANE_CONFIG_DIR
              This environment variable specifies the list of directories that
              may contain the configuration file.  Under UNIX, the directories
              are  separated  by a colon (`:'), under OS/2, they are separated
              by a semi-colon (`;').  If this variable is not set, the config‐
              uration  file is searched in two default directories: first, the
              current working directory (".") and then in /etc/sane.d.  If the
              value  of the environment variable ends with the directory sepa‐
              rator character, then the default directories are searched after
              the  explicitly  specified  directories.   For  example, setting
              SANE_CONFIG_DIR to "/tmp/config:" would  result  in  directories
              "tmp/config",  ".",  and  "/etc/sane.d"  being searched (in this
              order).

       SANE_DEBUG_GPHOTO2
              If the library was compiled with debugging support enabled, this
              environment  variable controls the debug level for this backend.
              A value of 128 requests maximally copious debug output;  smaller
              levels reduce verbosity.

       GP_DEBUG
              Set  to 1, 2, or 3, to enable various levels of debugging within
              the gphoto2 libraries.
